“Knit in stockinette, the most interesting aspect of this piece is the back opening, which elegantly swoops across the back and meets again at the bottom,” says Beatrice. She adds: “Be sure to double-check measurements along the neck, hem, and wrists, as these pieces are knit sideways and may not have as much stretch. If you find they don’t have enough give for you, you can finish the hems of the body and sleeves in a rib.”
